+# Day sixteen:
+
+Let's play a game! Yesterday you transformed your Barduino in a keyboard, now let's use it to play a game. Program yoou board to be able to use the arrow keys with th touchsensors (or use the code below) and play a game like [snake.io](snake.io) with it.
+
+!!! danger "Arduino Tips"
+    Like yesterday, if you use our code, you have to change the *USB Mode: USB-OTG (Tiny USB)* setting under *Tools* in Arduino. 
+    ![arduino usb otg](../../images/OTGMode.png)
+    Using this mode, you have to use *Boot Mode* to program the board (Press *Boot 00* button while reseting). When programming the board may change the *Port* number, so to programmed back you may need to change the port. 
+
+## Possible solution!
+
+### Arduino code
+
+```c++
+#include "USB.h"
+#include "USBHIDKeyboard.h"
+USBHIDKeyboard Keyboard;
+
+unsigned long values[] = {0,0,0,0};
+int direction[] = {KEY_UP_ARROW,KEY_RIGHT_ARROW,KEY_DOWN_ARROW,KEY_LEFT_ARROW};
+
+int dir = 4;
+
+unsigned long threshold = 40000;
+
+void setup() {
+  Keyboard.begin();
+  USB.begin();
+}
+
+void loop() {
+  unsigned long max = 0;
+  int max_i;
+  for (int i = 0; i < 4; i++) {
+    values[i] = touchRead(i + 4);
+    if (values[i] > max) {
+      max = values[i];
+      max_i = i;
+    }
+  }
+  //Serial.println("");
+  if (max>threshold && dir!=max_i) {
+    dir = max_i;
+    Keyboard.releaseAll();
+    Keyboard.press(direction[dir]);
+  } else if (max <= threshold) {
+    dir = 4;
+    Keyboard.releaseAll();
+  }
+}
+```
